Firebase Cloud函数模拟器未启动

Question

我一直在尝试使用云函数模拟器在本地测试我的云函数，但它似乎不起作用。当我运行时会发生什么：

firebase emulators:start

我得到以下信息：

i  emulators: Starting emulators: functions
+  hub: emulator hub started at http://localhost:4400
i  emulators: Shutting down emulators.
i  hub: Stopping emulator hub
Error: An unexpected error has occurred.
Having trouble? Try again or contact support with contents of firebase-debug.log

这就是我的firebase.json的样子：

{
"functions": {
"predeploy": [
"npm --prefix "$RESOURCE_DIR" run lint"
]
},
"emulators": {}
}

我试过几次运行firebase init，也试过firebase init emulators，但到目前为止都没有成功。

我登录的帐户具有编辑权限。请帮帮我，我真的很需要这个。

Answer 1

我也看到了这一点，但创建一个构建为我解决了这个问题，例如npm run build或yarn build

这将重新创建node_modules，并可能更新您的锁定文件以同步依赖

Answer 2

我试过多次运行firebaseinit，以及firebaseinit模拟器，但到目前为止都没有成功。

请参阅https://firebase.google.com/docs/emulator-suite/install_and_configure。

You will need CLI version 7.8.0 or higher to use the Emulator Sute.

一开始，你能检查一下你的节点版本和firebase版本吗？
